About Book Analytical methods that are portable, reasonably priced, and use simple instruments have been made possible by electrochemistry. Investigations and monitoring of biological samples, industrial products, and the environment also frequently employ electroanalytical procedures with a high degree of accuracy, precision, sensitivity, and selectivity. This book describes the detailed electrochemical terms and concepts engaged in the electrochemical reactions at the electrodes in electrochemical cells. Various types of electrode processes to display the electrochemical main features are concentrated. The basic electroanalytical cell systems and their practical electroanalysis are discussed simply. The book provides readers with a thorough grounding in the fundamentals of electrode reactions and the principles of electrochemical methods. The application of electroanalytical methods to chemical systems is the main prominence while the basic principles of electrochemistry are also discussed. Moreover, I am pretty sure that this book will improve the confidence of young researchers and students to think and remember electroanalytical concepts. I highly believe that this book will go a long way to satisfy the long-felt need of young researchers/students for a friendly guide on electrochemical analysis and sensors.
